英文: The results indicated that the REE tracer technology has high precision to quantify the spatial-temporal process of soil erosion; In earlier rainfall course, the development degree of sheet and nil erosion was general equation; Otherwise in the following
中文: 结果表明：REE示踪技术对定量研究土壤侵蚀具有较高的精度；降雨前期，片蚀与细沟侵蚀发育程度基本相当；后期细沟侵蚀占据坡面侵蚀的主导地位，其侵蚀平均加速度和平均侵蚀率分别是片蚀的15倍、9倍；试验结束，细沟侵蚀占据坡面总侵蚀的90%；本试验条件下，坡面下1/3区域为侵蚀活跃带。
